"I personally feel that this series doesn't recieve nearly the amount of praise that it should."

I completely agree! I was also a little wary about this show due to loving BTAS so much. But as I continued to watch it I liked it more and more - Bruce was an amazing Batman, but him mentoring Terry was just as great to watch.

It's great to have it on Netflix. I only watched the tv show. I saw some youtube vids where Bruce is his father or something like that. I never saw it and that is just a terrible idea and I'm glad I didn't see it.

Indeed but just when it was getting good it ends. Heck this was shorter than the Batman Strange Days short. It kind of felt like a tease in the end. And I really wanted to see Bruce & Terry fighting side by side against those robotic versions of Batman (one of each from Kane/Finger's, The Batman, B&TB, TDKReturns, Burton's, Adam West's, and Beware The Batman's), which was cool. In fact I wouldn't mind seeing a full episode of that. This also made me nostalgic for the actual Beyond show. Still very cool short overall.

Batman is experienced at flying and fighting, but he was unable to take down a squad of geeks on hoverboards they are not experienced to fly and maneuver very well. Not a moment of excellence for this show.

...it's funny, I HATED the show when it was running, (I remember back in the day they had to say it was a POSSIBLE future for BTAS because a lot of people felt the same). However I've grown to like it... I find it interesting how none of Terry's villains are as deranged and crazed as Bruce's...then again, you would HOPE that GOTHAM's mental illness problem has been taken care of...

Also...anyone see a lot of... Spider-Man in a couple of the villains...

So I'm guessing that Batman & Harley Quinn movie takes place after the flashback in Batman Beyond: Return of the Joker.
Or maybe I'm just guessing wrong, and that movie has zero to do with the cannon, though it celebrates 25 years of B:TAS.
